Understanding Streaming Quality Levels

Video quality is one of the most important factors in your streaming experience. Each quality level offers a different balance of visual clarity and bandwidth requirements.

SD (Standard Definition)

Standard definition typically refers to 480p resolution. It requires only three to five Mbps, is perfect for small screens, and uses significantly less data than higher resolutions.

HD (High Definition)

HD comes in 720p and 1080p (Full HD). 720p requires five to ten Mbps. 1080p requires ten to fifteen Mbps with sharp, clear picture on screens up to fifty inches.

4K Ultra HD

4K delivers four times the detail of Full HD. It requires twenty-five to thirty-five Mbps, is best on sixty-five inch or larger screens, and works best with HDR for expanded color and contrast.

Which Quality Should You Choose?

  1. Check your internet speed with a speed test
  2. Consider your screen size for visible benefits
  3. Evaluate your data cap for usage limits
  4. Test different qualities starting with 1080p

Data Usage Comparison

SD uses approximately one GB per hour. HD uses approximately three GB per hour. Full HD uses approximately seven GB per hour. 4K uses approximately fifteen GB per hour.
